Out of those two, I'd go for the Burton. I've always had Burton jackets, they're very durable, they usually look nice and they generally have a lot of features, always liked em!
This year however, I went for an O'neil jacket... Never really bothered to look into O'neil, but this jacket really surprised me, very warm, very comfy, lot of features, highly waterproof, not too thick... I really love it, I think this is one of the best snow jackets I've ever had. It was from the FIFTY2 series, so maybe try and look at those if you want something different
My experience with Burton outerwear is that it is cheaply made and does not hold up well. I had a pair of pants from a few years back that just wasn't worth the money. Right now im riding Volcom pants and jacket and couldn't be more happy. I also doubt you'd even be able to tell the difference between 10k and 8k waterproofing. All personal preference but id rather support Volcom.
